Title: Air fuel ratio control device of internal combustion engine
Inventor: TAKAHASHI ATSUSHI
IPC: F02D41/04
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To restrain the occurrence of a misfire due to abnormality of a fuel system in an internal combustion engine by correcting an intake air quantity so that the air fuel ratio approaches a target value when the air fuel ratio correction value is out of a designated range. SOLUTION: In an ECU 92 to which detection signals of a water temperature sensor 11b, a crank position sensor 14c, a cam position sensor 21b, an accelerator position sensor 26, an oxygen sensor 34 and a throttle position sensor 44 are input, the fuel injection quantity of a fuel injection valve 40 is corrected according to the air fuel ratio correction value depending on the air fuel ratio to converge the air fuel ratio on a target value. The air fuel ratio correction value is calculated so that as the air fuel ratio is lean to the target value, the more the fuel injection quantity is increased, and the air fuel ratio correction value is calculated so that as the air fuel ratio is rich to the target value, the more the fuel injection quantity is decreased and corrected.  When it is judged that the air fuel ratio correction value is out of a designated range, the intake air quantity is corrected so that the air fuel ratio approaches the target value.

Title: Volume type scroll system fluid machine
Inventor: MACHIDA SHIGERU
IPC: F01C1/02
Filed: 1982-10-05
Abstract: PURPOSE:To reduce gas leakage from an enclosed space and slide loss in same by setting the ratio of tooth height of a scroll lap to tooth thickness to at least 5 and the ratio of the tooth height to tooth groove width to at most 4. CONSTITUTION:When tooth height h, tooth thickness t and tooth groove width D of a scroll lap are represented by the same unit of length, the ratio of the tooth height h to the tooth thickness t of the scroll lap in a position except for the neighborhoods of the initial and last scroll positions of the scroll lap is set to at least 5. Consequently, leakage of gas can be restrained small for same gas and differential pressure. Also, when the ratio of the tooth height h to the tooth groove width D is set to at most 4, the leakage path is restrained from expansion caused by deformation to maintain always a compressor at high efficiency.

CONSTITUTION:A mold for molding a plastic is divided into an inner and outer molds, an item molding section is formed in the inner mold, a heat insulating material is filled between the outer and inner molds, and by heating or cooling only the inner mold the temperature control of the inner mold section can be effected. That is, a melted plastic 40 is injected from a gate 31 to form an item 41 in the item molding section 30. As a result, the passage of the electric current to heaters 35, 39 is cut, and cool water is immediately flowed into cooling pipes 34, 38. Consequently, since cold heat by the cold water is transferred via heat pipes 32, 36 to the inner molds 25, 27, they are cooled, the item is solidified and by opening the movable mold 22 the item can be removed. Thus, since the mold is divided into inner and outer molds, the inner mold has an item forming section, a heat insulating material is filled between the molds, and the temperature control of the inner mold section is effected quickly, the number of the working shorts can be substantially reduced.

Abstract: PURPOSE:To prevent occurrence of tight corner braking phenomenon by controlling a valve means which closes an orifice mounted on a discharge passage of a hydraulic pump which is driven due to difference of rotating speed of front and rear wheels depending on the operating condition of vehicle. CONSTITUTION:A hydraulic power transmission joint drives a hydraulic pump consisting of a plunger 17, a cam housing 18, etc. due to difference of rotating speed between a rotor 1 which transmits power to front wheels and a driven sprocket 7 to which driving force is transmitted from a rear wheel drive propeller shaft.

In this case, a controller controls the valve means 38 based on signals from a sensor which detects the operating condition of vehicle. For example, it does not lock the orifice 28 during running at a tight corner. Also it determines the timing of locking based on the function of differential rotating speed and duration time to lock the orifice, thereby preventing that tight braking phenomenon occurs and that temperature exceeds allowance temperature.
